WTF are you talking about? Please give examples for Trump. As I said before, I don't think you can because you're talking out of your media master's asses."Just because morons follow you, doesn't mean you support them." But with Goldwater and now Chump, their rhetoric gives aid and comfort to the crazies and racists/white supremacists.
For Goldwater, again, it came down to Constitutionality. He didn't believe it was Constitutional for the Federal Government to be able to tell businesses what they can and cannot do. Per the Constitution, that was supposed to be a state power, thus why he didn't support title 2 or title 7 of the Civil Rights Act of 1964.
